PROBLEM TO BE SOLVED: To solve the problem in household electrical appliances that household electric appliances are often left on, without anyone attending nearby or with an attendant, sleeping or after all the family members go out and this leads to wasteful electricity consumption. SOLUTION: An electric current detector is installed in a circuit breaker wiring in a household distribution board on a room-by-room basis or on a point- by-point basis. The result of the detection is indicated on a centralized monitor panel for monitoring the presence/absence of current flow, so that the state of use of electricity in each room or at each point can be monitored easily, to cut off an appliance wastefully consuming electricity. |
